Variable needle travelling arc in a scoop-stitch sewing machine |
摘要 |
A method for scoop stitching includes the steps of changing the angle of attack of a curved needle before and after penetration of the needle into a fabric. The needle moves along an arc around an axis. The axis is reduced prior to needle penetration and is increased after penetration to assure good penetration depth in thick fabrics.
